1 Claim.

This invention relates to an improvement in the book binding instructions. The closest prior art of which I am aware is found in the Morden Patent No. 908,596 of January 5, 1909. My improvements will be seen from the following disclosure.

Fig. l is an edge view of the improved book with filler, covers, and binding wire in assembled book form;

Fig. 2 is a perspective view of the cover portion alone showing the flange construction for holding the binding wire or rings to the covers;

Fig. 3 is an edge and Fig. 4 is a side view of a modified cover portion arranged for removably holding the binding wire or rings to the cover with the aid of a holding wire or rod; and

Fig. 5 is a detail View of a portion of a pack or filler construction in the preferred form for combination with the cover portion.

One of the main objects of the improvement is to provide a simple and economical means to cover a book filler, such as indicated, in Fig. 5, without using a back panel in the binding means but getting the eiiect of a back panel with respect to completely covering the back portion of the book.

To accomplish this object in one way, I provide a cover portion such as shown in Fig. 2. It may be made in one piece, but I prefer to make it in two pieces 5 and 6. These are two simple, flexible pieces of leather-like material. They are laid together with their outer faces one against the other vand their inner faces exposed. In this position they are stitched together along the lines a.-b and c-d. Between these lines I then punch a series of closely spaced holes I. The space 8 between each pair of holes is equal to the pitch distance 9 of the coiled wire binder element 3. The latter is threaded through the corresponding holes it in the binding margins of book leaves a and through the cover holes 1, all in one operation. Then each cover part is turned over from line c-d as a hinge, one part for the front of the book and one part for the back. It will be obvious from the description that the cover parts may be turned back when the book is opened and will lie perfectly flat one against the other, The leaves 5 of the book threaded on coiled wire 3 can be opened up at any part of the book and the book parts will all lie perfectly flat back to back in any opened position. In opened position the coiled wire 3 is exposed. But when the covers 5 and 6 are closed the coiled Wire 3 is not exposed at the back but completely covered. This has been accomplished by the two-part cover simply stitched together as stated, without any separate back panel, although the adjacent portions of the cover parts as they bend flexibly around the wire binder perform the function of a back panel in covering the binding ends of the pages and the coiled binding wire.

This type of coiled binding wire is well known in the art. So far as I know, the simple type of complete cover closure for the binding wire and bound pages along the bound edge of such a book, such as I have disclosed, is new. Ordinarily when a book filler of pages with the coiled wire binder is used with covers, the wire is exposed at the back or a book binding case is used with a back panel portion to which the covers are hinged, while the wire is fastened by some means on the inside of the back panel.

The species of my invention above described may be varied in various ways. For example, the flange ll inside the stitched lines c-d need not be of double thickness. Its width with respect to one thickness or ply may be shortened so that the holes to receive the binding wire 3 are made through only the other ply of the cover material.

Another species of the invention is shown in Figs. 3 and 4. In this form a series of open-ended slots l2 instead of holes is cut in the flange I I of the cover parts. A filler with coiled wire binder such as shown in Fig. 5 can be set between the covers so that the coils enter the slots. Then a retaining wire 5' is pushed longitudinally in the fold forming the cover flange. It is a convenience in this form to make the cover parts of a single piece. But if desired the ends of two parts may be stitched so the wire 5' will lie inside the outer row of stitches. This species makes a book having the advantages of the first described species and in addition provides means for interchanging the book filler so as to use the same covers over and over again.

Having disclosed my improvements, I claim:

In a book construction two separated pieces of cover material with adjacent end margins turned into flat abutting contact to make a perfectly flat two-ply flange, said flange being permanently held together, and at right angles to both cover pieces when the latter are laid out fiat, by two spaced rows of stitches one near the top of the flange and one near the bottom of the flange, a row of closely spaced holes made in said flange between its two rows of stitches, a pack of book sheets making a book filler having its margin provided with closely spaced holes, and a single wire looped through the holes in the margin of the pack and through the holes of said flange to hang from its back portion and so as to hold the filler the filler on the said flange, each cover piece beby a Wire binder in holes of the flange protected ing flexible and adapted to bend from th ba e and strengthened by a, row of stitching above and of the flange and lie against its adjacent side of below said row of holes.

the pack, whereby a book is provided with a peri'ectly fiat flange located inside and upstanding FRANK STANLEY SCHADE.
